There is no such thing. Useful computations are by necessity complex (in both a human-centric view, as well as from a computability view).
There are bad abstractions, of course. But this is just a hay dream that we can design a system that would be less complex than the essential complexity of the problem at hand - and dealing with all the hardware, networking, etc is just simply hard.
